DEVELOPMENT AND ASSESSMENT OF A NUMERICAL MODELLING CODE FOR THE THERMOPLASTIC PROFILE EXTRUSION COOLING STAGE
On the extrusion of thermoplastic profiles,upon the forming stage that takes place in the extrusion die,the profile must be cooled at a high rate to assure increased productivity,but avoiding high temperature gradients,to minimize the level of induced thermal residual stresses.These objectives are conflicting,since the increase of the cooling rate usually promotes higher temperature gradients.Due to the non-linear nature of the material behaviour and the large number of processing conditions involved,the employment of numerical modelling tools is mandatory to properly understand the system behaviour and to support its design.To model the profile extrusion cooling system,the temperature distribution must be computed both at the metallic calibrator and at the polymeric profile,which are in contact through a common interface.
